environmental impact is limited to contribution to the greenhouse effect due to electricity consumption and due to possible refrigerant leakages. Due to the higher efficiency of the geothermal heat pumps (COP = 4 to 6) compared with air source heat pumps (COP = 2,5 to 3,5) and fossil fuels (efficiency = 80-90%),
Enlightening the World, 1886. A landmark at the entrance to New York Harbor since 1886, the Statue of Liberty is a national and international symbol with multiple meanings.ntended as a sign of friendship between the United States and France and as a monument to political liberty in both nations, it has come to represent a broader vision of freedom and democracy and the promise of a better life for the millions of immigrants who passed by her as they entered the country.
The sculptor who masterminded the Statue of Liberty, Frederic Auguste Bartholdi, envisioned it as a symbol of liberty, hence the official name of âLiberty Enlightening the Worldâ. But his symbol was of liberty spreading outwards to the world from America, rather than liberty for those incoming. Ellis Island only became the first stop for immigrants in 1892, i.e. six years after the statue was erected, remaining open for business until 1954.
